A Specification of Lettera Patent.

Patented oet. e. 1907.

Application filed January 18, 1997. Serial No. 852.884.

To all whom it may concern:

Be it known that I, LEONARD Bnn'rnm'r, a citizen of the United States, residing at New York, borough of Brooklyn, in vthe county of Kings and State of New' York, have invented a new and useful Seal for Bottles, of

the thickness of the gasket, or sealing ring.

The invention is illustrated in the accompanying drawing, in which- A Figure 1 is a side elevation of a bottle seal constructed according to my invention; Fig. 2, is a central vertical section thereof applied to a bottle; Fig. 3, is a similar view of a modified form of construction; and, Fig. 4, is a vertical section of a seal applied to a. bottle with an irregular locking shoulder. i

In the accompanying drawing, the "several pai'ts of my invention are indicated by numeralsof reference; and in practice I provide a bottle seal similar in every way to the seafl known generallyas the Crown seal, except that `the crimps in the skirt instead of being made even, or of equal depth, as in the fCrown.cap, are made of different lengths, or depths, for purposes hereinafter described.

In making the Crown cap, it was presupposed that a bottle could beprovided having uniform locking shoulders so that-if the different scallops, or crimps were f of a uniform depth,and proportioned to the sealing disk inclosed in the cap, when the flaring skirt of the cap was forced inward against the locking shoulder by the capping machine head, all of the inward projections of the several scallops would engage the said shoulder, and hold the seal with the lip of the bottle v forcibly embedded in the gasket. 'In fact, however,

the locking shoulders on bottles are not uniform in depth, nor are these shoulders uniform throughout their extent ,on the same bottle so that it often happens when the pressure block of the capping head forces the seal down to embed the lip of the bottle therein, a part of the inward projections of the scallops are below the locking shoulder and will not 'engage the shoulder when forced inward by the locking head until the return of the pressure block from contact with the cap, when the entire' seal will rise until the projections come in contact with the shoulder. In many cases this rising is not sufficient to allow ofthe escape of all the gases contained in the inclosed liquid providing the same is used within a week or two, although a large percentage of the gas will escape rendering the liquid somewhat flat In many cases, however, all thegas is allowed to escape, and the inclosed liquid is lost. In other cases, should vthe locking shoulder be a little thicker than the average,

the scallops will not be forced downward far enough for the inward projections to engage the locking shoulder at all, when the cap will be driven off the bottle immediately, requiring another seal.' f f In my invention, as shown in the drawing, 5, represente a bottle cap, having a crimped skirt 6, the several scallops of which are on different planes,-as shown in the drawing, being on three planes so that the inward projections 7, 8, and 9, are at different levels on the skirt, and lthese several crimps, or scallops run in series so that there are only two scallops intervening between two scallops of the same plane. Consequently, should the locking shoulder l0, of the bottle :be uniform in thickness every third, scallop 7, 8, or 9, will engage the' side 11 is thicker than the side 12, either the crimps, or

scallops 7, or 8, will engage the side 11, and the scallops 9, ,or`8, the side 12, as will be understood, andwhen the pressure block of the capping head is removed from contact with the seal, there will be no return of the seal to allow of the escape of any gas, `but both sides of the seal will be held equally firm, as will be readily understood.

In placing. the seal on a bottle, the scallops which are on the planes higher than thescallops required,

lwill have the inward projections fiattened on the outer surface of the locking shoulder without interfering with the action of the other scallops, while the projections on the scallops lower than the -ones required will simply enter the groove 13, below the locking should'er.

With this improved cap, I may use the usual cork disk, or a cork ring, as 14, and I may also use a cap with a recessed center 15, as shown in `g. 3, to provide for i regular tool not be shape of a cork sealing ring, I do not confine the invention to the construction or use of other parts shown, as the stepped skirt may be applied with other gaskets than the ones shown; and may also be applied in connection with the construction shown and claimed in a companion application executed by me this day (Serial No. 352,885, ilod Jan. 18, 1907); or `it may be used in commotion with any construction of cap where a crimped locking skirt is used.

Having thus described my invention, what I claim as new and desire lo secure by Letters Patent oi' the United States, is-

l, A seal for bottles comprising a cap. und gasket, said cap having a crimped skirt with the several scallops il'- rcguinr in distance from the edge of the skirt.

in a hotilc scai. a cap having a crimped skirt with scallops in diil'crcnt planes.

3. ln a bottle seal, a cap havinp,r a crimped skirt with scallops in different planes, said scallops beim.: in series.

4. in a bottle seal, a cap having n crimped skirt with scallops in diifcl'entvplanes, said scallops heim.: in-serles advancing from the lowestv plane successively to the highest. nud the highest succeeded immediately by the lowest.

i. In a bottle seal, a csp havim.v s crimped skirt with the scallops in three diii'erent planes, said scallops beim; 20

in series whereby but two scallops intervene between nny two scallops in the same plane, ns and for the purpose set forth.

`(l. 'lhe herein described seal for bottles comprising a 'cap nud gasket, said'cnp having a crimped skirt with the LEONARD BARTLETT.
